Planned Parenthood is the main source of health care for a lot of women in underserved locations--losing those screenings means that many of them are losing the chance to catch breast cancer in its early stages.

Why were the funds revoked? Komen says this that it recently changed its funding guidelines to exclude any organization under investigation by Congress (an investigation into Planned Parenthood had been opened by Republican Rep. Cliff Stearns).

For its part, Planned Parenthood says that Komen was under pressure from anti-abortion groups--and some of those groups definitely reacted happily that Komen had pulled the funding. The Alliance Defense Fund offered praise to the organization "for seeing the contradiction between its lifesaving work and its relationship with an abortionist that has ended millions of lives."
